App Development

Building apps — whether mobile (iOS/Android) or web-based SaaS products — is the side hustle with the highest potential for building a sellable asset. A successful app generates recurring revenue, scales without additional labor, and can eventually be sold for 3-5x annual revenue on acquisition marketplaces like Acquire.com.

The 2026 landscape is more accessible than ever. React Native and Flutter let you build cross-platform mobile apps from a single codebase. Next.js and Supabase let you build full-stack web apps in days. AI coding assistants (Claude, Cursor, Copilot) have genuinely 2-3x'd development speed for experienced developers. The bottleneck is not building — it is finding a problem worth solving.

The most successful indie app developers scratch their own itch. They build tools they personally need, launch them for free or cheap, iterate based on feedback, and gradually add premium features. The goal is not to build the next Instagram — it is to build a tool that 1,000 people will pay $10/month for. That is $10,000/month from a single product that you maintain in a few hours per week.
